What is the bore size and compression distance for these pistons?

These pistons are designed for a 4.280-inch bore. The compression distance is 1.395 inches, and they utilize a 0.990-inch wrist pin.

Are these pistons suitable for street use?

While forged from high-strength 2618 aluminum for performance applications, features like the FSR design and optional skirt coating can contribute to reduced friction and noise, potentially making them suitable for certain street performance builds. However, they are not CARB approved for use in California.

What material are these pistons made from?

These pistons are forged from 2618 aluminum, a material known for its high tensile strength which is necessary for high-demand performance applications like racing engines.

Product Details

If you're building a high-performance Big Block Chevy engine, getting the right pistons is crucial for durability and power. This set of eight JE Pistons is forged from 2618 aluminum, a material chosen for its high tensile strength, making it well-suited for the demands of racing and performance builds. They are manufactured entirely in the USA, reflecting JE Pistons' long history in the performance parts industry.

These pistons feature JE's proprietary Forged Side Relief (FSR) design, which uses a reduced skirt width to minimize friction and power loss, while also saving weight. Depending on the specific application, they may also include an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power delivery. Some applications also benefit from a skirt coating that further reduces friction and wear on the cylinder walls, contributing to a quieter engine operation and longer component life. Each piston is designed specifically for the Big Block Chevy engine and its intended use, ensuring optimized performance and durability.

This kit includes pistons for an 8-cylinder engine with a 4.280-inch bore, a 1.395-inch compression distance, and a 0.990-inch wrist pin. Please note that these pistons are not CARB approved and cannot be shipped to California. They are also subject to California's Proposition 65 warning.
